Technology & AI Practice and Review

Worked answer: No. Test mandatory workflow requirements first. A low price cannot compensate for a requirement the process must meet. Include implementation, support, access, integration, and exit costs in the comparison.

Worked answer: A representative end-to-end task, including required inputs, review, exceptions, output, and recovery. A polished feature demonstration is not evidence that your actual workflow works.

Worked answer: You need to understand how records can be retrieved, reconciled, retained, and moved if the arrangement changes. An exit plan is easier to assess before the system becomes indispensable.

Worked answer: Very little by itself. Trace material claims to appropriate evidence, check omissions and calculations, and assess the result against the task requirements.

Worked answer: No. Agreement is not primary evidence and can repeat the same unsupported assertion. Inspect actual sources or use another suitable verification method.

Worked answer: No. Distinguish preparing a recommendation from authority to send, publish, edit records, or execute another action. Apply the intended workflow’s review and authorization.

Worked answer: Manual time is 1,200 minutes, or 20 hours. New handling is 240 + 240 = 480 minutes, or eight hours, plus two monitoring hours. The modeled release is ten hours monthly.

Worked answer: Net modeled value is $300 − $90 = $210 monthly; $1,050 ÷ $210 = five months. This does not prove cash savings or cash payback if the labor cost is unchanged.

Worked answer: No. The destination may already have created the task. Use stable identifiers, appropriate duplicate protection, bounded retries, and reconciliation of uncertain outcomes.

Worked answer: There are 100 required-item opportunities. Omission rate is 8 ÷ 100 = 8%. Fourteen drafts have no required-item omission, so draft completeness pass rate is 14 ÷ 20 = 70%. These are different measures.

Worked answer: No. Critical requirements should be explicit release conditions. Correct and recheck affected drafts rather than averaging the issue away.

Worked answer: It is a four-percentage-point decrease, or a 40% relative decrease because (10 − 6) ÷ 10 = 40%. Preserve the intended meaning and denominator.

Worked answer: No. The parent order total has been repeated at the line grain. Aggregate at the appropriate grain or use the correct line values.

Worked answer: No. It can establish that a referenced record exists under the defined constraint. Correct real-world matching still needs appropriate evidence and checks.

Worked answer: No. Transaction guarantees apply within their defined boundary. External actions need their own confirmation, reconciliation, and recovery design.

Worked answer: Not on count alone. Check unique identifiers, expected values, relationships, exclusions, and source samples. One missing record and one duplicate can leave the same count.

Worked answer: Attendance is 100%, sign-in is 90%, and demonstrated task completion is 75% of the invited cohort. These measure different things; investigate why task completion falls short.

Worked answer: Gross release is 1,200 minutes, or 20 hours. Subtract six support hours to get 14 hours monthly before other omitted effort. Check comparable work, quality, and whether the result persists.
